Application June 6, 1956, Serial No. 589,668

1 Claim. (Cl. 116-419) This invention relates to a book marker of novel structural features which facilitate its manufacture and make it highly etficient and practical in use, and further relates to a novel method of manufacturing the same.

These and other advantageous objects, which will appear from the drawings and from the description hereinafter, are accomplished by the structure of my invention, of which an embodiment is illustrated in the drawings. It will be apparent, from a consideration of said drawings and the .following description, that the invention may be embodied in other forms suggested thereby, and such other forms as come within the scope of the appended claim are to be considered within the scope and purview of the instant invention.

In the drawings:

Fig. 1 is a fragmentary, perspective view showing steps in the manufacture of a book marker pursuant to the invention,

Fig. 2 is a fragmentary, vertical sectional view of a support member on which the base members and ribbons to be used in making the book marker of the invention may be positioned showing the die member about to descend thereon.

Fig. 3 is a fragmentary, perspective view of the parts fused on completion of the operation shown in Fig. 2,

Fig. 4 is a fragmentary, perspective view which shows the step of cutting the base member intermediate opposite ends thereof to form two book marker units,

Fig. 5 shows a step in initially flexing the book marker for insertion into the pocket 12 between the bookcover and the bound edge of the pages thereof,

Fig. 6 shows the next step of inserting the book marker base into said pocket and permitting it to expand therein to hold it in place, and

Fig. 7 is a top plan view of a book marker embodying the invention.

As shown in the drawings, the book marker 10 of the present invention (Fig. 7) comprises a flexible base member 11 of proportion to snugly fit into the pocket 12 of a book, said pocket being defined by the cover 13 of the book and the bound edge 14 of the pages 15 of said book. A plurality of ribbons 16-16d (which may be of contrasting colors as shown in Fig. 7, wherein the ribbons are sectioned for colors contrasting as indicated in the Patent Office chart), are secured, at one end, to the marker base and extend therefrom. Thus, when the marker base 11 is inserted into the pocket 12 (Fig. 6) the ribbons may be inserted at the desired pages of the book to mark the same. The flexible base member 11 may he made of any suitable plastic or other material to which the ribbons are secured.

Fig. 1 illustrates one of many forms of apparatus useful in making the marker of this invention and in carrying out the method of the invention, including a support 17 and a plurality of spools 18, 18a, 18b (of the desired number and color) the ribbons being passed from said spool or other source and over the top of support 17. In a convenient form of the invention (Fig. 1) the base member comprises a pair of flexible strips 11, 11a which are secured together under pressure with the ribbons inserted and sealed therebetween (Fig. 2). Base member 11 may be positioned in a recess 19 in support 17, and a heated die 20, which may have the face thereof formed to impress a religious or other message, into the base member, is preferably heated and brought downwardly under pressure to fuse the base member 11 and ribbons. The die 20 is then elevated and the unitary base member strips 11, 11a, and ribbons therebetween, may be removed from the recess 19 and the ribbons cut to the desired uniform length (Fig. 7), by any suitable cutting means so as to extend from the base member for a predetermined length.

if desired, the form shown in Fig. 2 may be used to manufacture a pair of markers 10, 113a (Fig. 4) in one operation, by positioning a plurality of ribbons across the base member strips so as to extend from opposite ends thereof, securing the base member strips to the ribbons inserted therebetween and extending from opposite ends thereof, and the cutting said base member intermediate the ends from which the ribbons extend, as shown in Fig. 4, by use of a suitable cutter 21, to divide the base member into two base members 10, 10a with ribbons extending from one edge of each base member. If desired, suitable guides 22 may be provided on the support for guiding the ribbons toward the base members.

The base members may be made of a heat-fusible material so that, on application of heat and pressure (Fig. 2) the material of the base member will become soft and the ribbons will adhere thereto, or said base member may be made of a heat-stable material and the ribbons glued or otherwise secured thereto, within the spirit and scope of the invention.

I claim:

A religious marker for insertion between the bound edges and cover of a book, comprising a substantially fiat, flexible base member of heat sensitive material, a plurality of elongated, open mesh ribbons disposed in spaced parallel relationship on said base member, the said base member thermally enveloping at least one end of said ribbons and passing through the meshes of said ribbons and defining therewith a unitary integral base and ribbon structure, ribbons unitarily bonded to said base member and extending therefrom in parallel spaced rela tion for insertion in different portions of the book, to facilitate selection of that portion of the book marked by the color of the ribbon so inserted therein.
